Changes with Aloha.Editor 1.2.27

Bugfix SUP-1165

When clicking on a nested editable, the selection-changed events where
not triggered when the actual target of the click was not the editable
itself (e.g. when clicking on formated text). This has been fixed.

Bugfix SUP-1193

After interacting with a dialog, the Aloha editor lost the the
link scope although the current selection was inside a link.
This has been fixed.

Bugfix SUP-1389

Drag & drop of inline blocks in table cells was not possible and
has been fixed now.
